研究人员开发了一种新方法来理解深度伪造语音检测器如何做出决策。通过在自监督表示上使用集成梯度，该技术可以精确定位音频中检测到深度伪造证据的特定时刻。分析显示，不同的检测器，如AASIST、CA-MHFA和SLS，依赖于不同的音频线索，范围从环境声音到音素伪影和频谱完整性。 AI
影响 为用于检测合成媒体的AI系统的决策过程提供了关键见解。

深度伪造语音检测器究竟听到了什么？
arXiv:2606.10912v1 Announce Type: cross Abstract: Deepfake speech detectors often output a single score without explaining why an audio sample is flagged, where in the signal the evidence lies, or what cues drive the decision. We propose an audio-native explainability pipeline us…

深度伪造语音检测器到底听到了什么？
Deepfake speech detectors often output a single score without explaining why an audio sample is flagged, where in the signal the evidence lies, or what cues drive the decision. We propose an audio-native explainability pipeline using Integrated Gradients on time-aligned self-supe…
